Аннотация:Ecological intactness--the absence of serious human disturbance over long periods of time and large areas--is a quality of a natural landscape that, once destroyed, cannot be artificially restored. Yet large, intact forest landscapes are quickly becoming rare in most parts of the world. Perhaps surprisingly, the extent and boundaries of the world's intact forests are poorly documented, including those in the Northern Hemisphere.Identifying and delineating these boreal (northern) landscapes is a difficult but urgent task. It is urgent because industrial land use is rapidly expanding. To exercise caution in development, governing bodies, as well as the forest and mineral industries, need to know the precise boundaries of these intact ecosystems. It is difficult because many of these landscapes are large, inaccessible, and poorly known. With this in mind, Global Forest Watch (GFW)--an international effort to map the condition, development threats, and key actors in the world's forests-launched the Pan-Boreal Mapping Initiative, a unique and rigorous effort to map the last remaining wildlands of the boreal.
